Comment(by maeder):

 The text package should be installable meanwhile by "cabal install", The
 network package had too strict constraints for dependencies. I downloaded
 it and relaxed them.

 {{{
 -bash-3.00$ diff network.cabal~ network.cabal
 42c42
 <     base >= 3 && < 4.6,
 ---
 >     base >= 3 && < 4.7,

 -bash-3.00$ diff -w Network/BSD.hsc~ Network/BSD.hsc
 115c115
 < import Prelude hiding (catch)
 ---
 > import Prelude
 }}}
